CarbOthello pastel pencils

I would like to carry out a research on pigments light fastness and
durability of CarbOthello pastel pencils. Before I start I would
like to ask if you know if anybody has already carried out this kind
of research so I would be able to compare the results or focus on
other aspects of work with Carbothello, not to duplicate somebody's
work.
